Advisory Steps
Fabric-First Upgrade Strategy (SR54 Grounded)
1. Fabric-First Insulation
Seal thermal leaks before upgrading heating hardware. External wall wrap and 300mm attic insulation slash U-values from 2.10 to 0.18 W/m²K.
Step 1 • Up to €10,500 Wall + Attic Grant2. Heat Pump & SR50 Readiness
Replace old oil or gas boilers with an Air-to-Water Heat Pump once your home passes the HLI heat loss test (≤ 2.0 W/K·m²).
Step 2 • Up to €12,500 Heat Pump Grant3. Solar PV Microgeneration
Generate clean electricity on-site to offset day-rate power costs and export surplus back to the grid under the 24c/kWh Clean Export Guarantee.
Step 3 • Up to €1,800 Grant (0% VAT)4. SEAI One-Stop-Shop vs Step-by-Step
Navigate Individual Energy Upgrade Grants or One-Stop-Shop Deep Retrofits without contractor markups or paperwork delays.
